LLMServingSim

Toward unified simulation of heterogeneous and disaggregated LLM serving infrastructure

Measured execution costs

Powered by a vLLM-based layerwise profiler, with reproducible TTFT, TPOT, and latency comparisons against recorded Llama and Qwen workloads.

Heterogeneous HW

Mix GPU, CPU, CXL, and PIM tiers. Drop in any hardware target via the per-hardware CSV bundle format.

Disaggregated serving

First-class TP / PP / EP / DP+EP support across multiple instances, with wave-synchronized expert collectives on multidimensional ASTRA-Sim topologies.

Real workloads

Drive the simulator with ShareGPT-style traces or closed-loop agentic sessions (sub-requests + tool calls) for SWE-bench-style scenarios.
